[0002] During wastewater treatment and purification, a large amount of scum and floating solids often accumulate on the surface of the wastewater treatment pond. Therefore, it is necessary to manually or with specialized equipment scrape off and collect the scum.

[0003] Currently, most of the scum generated in existing sewage treatment ponds is removed manually using hand-held scoops. However, manual cleaning is time-consuming, labor-intensive, and inefficient. Therefore, in order to achieve faster removal of scum from sewage treatment ponds, reduce workload, increase efficiency, and promote technological advancement and enhance core technological competitiveness in the industry, this application proposes a new implementation scheme that differs from existing scum collection devices for sewage treatment ponds. Utility Model Content

Two first electric actuators are fixedly connected to the top of the first mounting frame, and a second mounting frame is fixedly connected to the bottom of the two first electric actuators. The bottom of the second mounting frame has multiple drainage holes. Connecting plates are fixedly connected to both sides of the second mounting frame. The top of the connecting plates and the top of the second mounting frame have the same sliding groove. Two connecting blocks are slidably connected within the sliding groove. A filter screen is fixedly connected to the bottom of each connecting block and is disposed within the second mounting frame. A second electric actuator is fixedly connected to the top of the connecting plate, and one end of the second electric actuator is fixedly connected to the connecting block.

[0006] Furthermore, the moving mechanism includes a lead screw, which is rotatably connected to one side of the sewage tank. A motor is fixedly connected to one end of the sewage tank, and the output end of the motor is fixedly connected to one end of the lead screw.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figures 1-4 A scum collection device for a sewage treatment pond includes a sewage pond 1, a moving mechanism, a first mounting frame 8, a control panel, and a processor. The processor and the control panel are connected by wires. The processor is an ARM9TDMI. Two first electric push rods 10 are bolted to the top of the first mounting frame 8. The bottom ends of the two first electric push rods 10 are bolted to a second mounting frame 11. Under the tension of the first electric push rods 10, the second mounting frame 11 moves downward, thereby realizing the lifting and lowering of the collection device so that the collection device can be submerged in sewage. The bottom of the second mounting frame 11 is provided with multiple drainage holes 12. Sewage is discharged from the second mounting frame 11 through the drainage holes 12. Connecting plates 13 are welded to both sides of the second mounting frame 11. The top of the connecting plate 13 and the top of the second mounting frame 11 are provided with the same sliding groove 14. Two connecting blocks 16 are slidably connected in the sliding groove 14. The bottom of the connecting block 16 is fixed with a filter screen plate 15 by bolts. The filter screen plate 15 is set in the second mounting frame 11. Scum enters the second mounting frame 11 with the sewage. The sewage passes through the mesh of the filter screen plate 15, and the scum is intercepted and collected in the second mounting frame 11 by the filter screen plate 15. The top of the connecting plate 13 is fixed with a second electric push rod 17 by bolts. One end of the second electric push rod 17 is fixedly connected to the connecting block 16. Under the drive of the second electric push rod 17, the connecting block 16 moves in the slide groove 14, thereby driving the filter screen plate 15 to move outward, and then scraping the scum off.

[0019] The moving mechanism includes a lead screw 5, which is rotatably connected to one side of the sewage tank 1. A motor 7 is fixed to one end of the sewage tank 1 by bolts. The output end of the motor 7 is fixedly connected to one end of the lead screw 5. The outer wall of the lead screw 5 is threadedly connected to the first mounting frame 8. A sliding rod 6 is welded to the other side of the sewage tank 1. The other end of the first mounting frame 8 is slidably sleeved with the sliding rod 6. Driven by the motor 7, the lead screw 5 rotates, thereby causing the first mounting frame 8 to move along the sliding rod 6, which in turn drives the collection device to move back and forth horizontally.

[0020] Both ends of the sewage tank 1 are bolted with collection boxes 3 for easy collection of scum. A baffle 4 is slidably inserted into the bottom of the collection box 3. When the baffle 4 is pulled out from the bottom of the collection box 3, the scum inside the collection box 3 falls downward so as to discharge the scum inside the collection box 3.

[0021] A handle is bolted to the bottom of the baffle 4, and an anti-slip pad is glued to the outer wall of the handle to facilitate operation with the baffle 4.

[0022] Both sides of the first mounting frame 8 are fixed with protective telescopic sleeves 9 by bolts. The other end of the protective telescopic sleeves 9 is fixedly connected to the sewage tank 1. They can extend and retract as the first mounting frame 8 moves, preventing sewage, scum and external debris from contacting the screw rod 5, avoiding corrosion or jamming of parts, and extending the service life of the equipment.

[0023] A protective box 18 is fixed to the top of the connecting plate 13 by bolts. The protective box 18 covers the outside of the second electric push rod 17, preventing sewage, scum and water vapor from contacting the second electric push rod 17, preventing the components from rusting and short circuits, and ensuring its normal operation.

[0024] A sewage pipe 2 is sealed and connected to one side of the sewage tank 1 to achieve directional discharge of sewage, which facilitates subsequent centralized treatment.

[0025] The processor is connected to the motor 7, the first electric actuator 10, and the second electric actuator 17 via wires.

[0026] The working principle of this embodiment is as follows: In the initial state, the first mounting frame 8 is located at one end of the sewage tank 1. Then, the two first electric actuators 10 are started simultaneously through the control panel. Next, the processor controls the two first electric actuators 10 to operate synchronously. Under the tension of the first electric actuators 10, the second mounting frame 11 is moved downward, thereby moving the filter screen plate 15 downward until half of the filter screen plate 15 is submerged in the sewage. Then, the motor 7 is started through the control panel. Under the drive of the motor 7, the lead screw 5 rotates, thereby causing the first mounting frame 8 to move along the slide rod 6, thereby moving the filter screen plate 15 to the other end of the sewage tank 1. During the movement, the scum enters the second mounting frame 11 with the sewage. The sewage passes through the mesh of the filter screen plate 15, and the scum is intercepted and collected by the filter screen plate 15 in the second mounting frame 11. When the first mounting bracket 8 moves above the collection box 3, the first electric push rod 10 is retracted via the control panel, and the second mounting bracket 11 is retracted. During the ascent, sewage is discharged through the drain hole 12 until the second mounting bracket 11 is moved above the sewage tank 1. Then, the second electric push rod 17 on the side near the collection box 3 is activated via the control panel. Driven by the second electric push rod 17, the connecting block 16 moves in the slide 14, thereby driving the filter screen plate 15 to move outward, and scraping the scum into the collection box 3. Then, the scum is collected according to the above steps. Finally, the baffle 4 is pulled out from the bottom of the collection box 3, and the scum inside the collection box 3 falls downward, thereby exporting the scum inside the collection box 3.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
